ELASTIC-FLUID QIOTOR.

To all whom it may co'nccm:

spend therein.

Be it known that I, CHRISTOPHER J HN (formerly JOHN (ntusrornnn LAKE),

LAKE a citizen of the U nited States, and resident unty of Fairfield andof Bridgeport, in the co State of Connecticut, have invented certain newand useful Improvements in Elastic- Fluid Motors, of which the followingis a specification.

This is a divisional application pertaining to subject-matter sho myformer application filed J anuary 4, 1906, Serial Number 294,552,and'which was divided out of the claims in said former applicationpursuant to a requifement'of division in Ollice letter of October 6,1906.

"The present invention consists in certain new and useful improvementsin elastic fluid motors for the conversion of the kinetic en ergy ofpower fluids into useful mechanical power.

The object of m invention is to produce a rotary engine in w rich thepower fluid will be distributed over the largest number of impactsurfaces at the maximum volume and velocity constantly maintained throu'hout the engi11e-ei1cuit, an(l therefore, with the highest efficiency.

A further object is to produce an engine in which the direction ofrotation may be readily reversed and which will operate at itshighestefiiciency in either direction.

A further object is to produce an engine in which water or other liquidcondensed therein will be constantly. and automatically removed withoutany escape of the powerfiuid.

V-fith these objects in view and further objects which will appear asthe nature of my invention'is more fully set forth, I have produced anengine that embodies one form of my invention as hereinafter describedby reference to the annexed drawings, in which:

The gate 69 and the link71 are duplicated on the opposite side of t nected in such manner heblock 72 and conthat the inlet and exhaust pipes res ectively willcommunicate tangentially wit i either side of the wheel according to theposition of the block 72 which is shif table by means of lever 73 andlink 74, shown in Fig. 1, for moving it along the periphery of the wheelto pipe.

The arrangement of in exhaust conduit 68 around my inlet conduit n2 isalso an important feature of my invention. 'lhis arrangement allows-thepower lluid to act upon a given unit of impact surface of the wheelthrough nearly an entire revolution before coming to the point ofexhaust. 'ihis late exhaust is especially desirable in connection withmy special l'ortn ol' wheel in which nearly the. entire grow-edperipheral portion is constantly and continumislv under the iniluenceot' the power lluid. My arrangement of the exhaust passage around theinlet has also the further advantage of providing a convenient exhaustopening from either side of the wheel without du lication of pipes forthat purpose, and it a so prevents excessive radiation from the inletpipe. and consequent loss of power.

The pipes 76 areplaced in the casing 64 to provide an outlet for anycondensation that may collect in the bottom of the casing. These pipesare bent into a U shape and kept filled with liquid whichpreventsesapeol' the gaseous power lluid l'rom the. casing. The pipes placedinopposite sides of the casing at about its mid-height so that one ofthem will carry of? the liquid in the. exhaust side of the.wheel inwhatever direction it may be. running. These passages may be. omitted inany case where it is desirable to invert the. engine or where the powerfluid is such that condensation is not met with.
